		+	* [[User:Etienne Robillard\|Etienne Robillard]] 08:13, 22 February 2013 (EST) Calcium disodium EDTA is added in trace amounts to diet drinks (in particular Mountain dew), perhaps as a NMDA antagonist to induce cognitive impairments on population drinking soft drinks loaded with [[phenylalanine]], a aspartame precursor, to limit and impair their cognitive capacities to learn and defend their own homes from bioterrorism, for example.
